Subtract g(x) from f(x): (x²+3x-1)-(x³+4x²+1)=-x³-3x²+3x-2
C is the correct answer.
Answer:
No solution
Step-by-step explanation:
the perimeter of rectangular: 2 x (B+L)
2 x (40 + L) = 20
80 + 2L = 20
2L = -60
L = - 30 .... length can't be negative
Answer:
Yes, Kevin skied twice as long as Lori without falling.
Step-by-step explanation:
Kevin's time was 223 sec and Lori's was 110 sec.
110 x 110 = 220
Since Lori's time was 110 seconds and twice that is <em>less</em> than Kevin's, which was 223.
Thus we have our answer:
Yes, Kevin skied twice as long as Lori did without falling.
Hope it helps!!
Answer:
Volume: 45000cm^3
Surface area: 6600cm^2
Step-by-step explanation:
The volume is all the side lengths multiplied, so 60*25*30 = 45,000 cm^3.
Now let's calculate the surface area.
The bottom is the width * the length, or 60*25 cm^2.
One of the sides is the length * the height, or 60*30 cm^2. This is multiplied by 2 because there are 2 of those sides.
The other pair of sides is the width * the height, or 25*30 cm^2, again multiplied by 2.
In total, the surface area is
60*25+2*60*30+2*25*30 = 6600cm^2
